Puncher – Did you know?<br />
Punchers with three cutting tips as standard<br />
The waste drops easily out of the die, if you turn the punch 2-3 turns further<br />
into the die using a spanner after the punching operation. ➊<br />
This pushes the waste piece over the edge of the die and so falls freely out<br />
of the die if you have predrilled 11 or 21 mm. ❷<br />
